Combination Square Parts

[Jerry Bruette]

I have a Craftsman combination square that no longer clamps in position. The nub that rides in the groove is rounded over and no longer holds. Are repair parts available? Here's a picture of what I need.

Wonder if you purchase one from HF if inners would work?

Craftsman doesn't do this kind of thing anymore. If you really want to try to repair your square, I would search ebay for a used Craftsman combination square. That being said, you can get really cheap combination squares from Amazon / Home Depot.

I have one that looks just like that.
Now I have a steel straight edge and a setup angle block, instead of a combination square

But I'd rather have the square.

Just buy a new square! I have a craftsman combo square I got years ago when I had a giftcard to Sears. It wasn't very expensive and there are plenty of equal quality squares on the market in the same quality level for under $20. I also have a woodpeckers combination square and the indexable stops and holes for marking your work are really a world of difference, however I am sure you know it will not be cheap.

Wonder if Starrett would fit? Probably cheaper to buy a decent quality square then new Starrett parts.

I had to buy that piece from Starrette , Don’t know if it would fit a different brand. I don’t think it had broken, think I was cleaning and
oiling it ….that’s how stuff gets lost ! The piece was cheap and sent quickly.

I have a blemished PEC that I picked up on the Bay a year or two ago. It is a fairly decent combo square. Not a Starrett but perfectly servicable. The main difference from the Starrett is that the gradations are photo etched on the PEC vs mechanically etched on the Starrett, which means they aren't quite as easy to read for old eyes.

I think the "blemish" was a little variation in how dark the gradations were, but I am not certain.

I picked up a few blemished PEC double squares from Harry Epstein--wonderful and i have no idea what the blemishes are. (i am addicted to double squares--incredibly handy to me, your mileage may vary!!)

I think the Empire combination squares at Home Depot are made in the U.S. if that matters. Are Empire squares equal in quality to the better Starrett? Most probably not but I can't measure the difference in accuracy. Readability? Starrett is probably better but again, I can read the Empire just fine. PEC is another quality brand and may be available as seconds from Harry Epstein but I have no experience with them.

This is what I would do, unless the Craftsman has special meaning to you. New combination squares are pretty cheap and are going to most likely be more accurate than old ones. A lot of older tools are better made than newer ones. But squares aren't one of them. Modern machines do a better job with accuracy like this than old machines or human hands.

I have the Empire square, and the only real downside I've noticed with it in the last 5 years of owning it is the numbers are printed on, not etched. But they haven't worn off yet, so that hasn't become a problem. I don't know how accurate it is, but if I score a line, flip the square over and score another line, they run parallel. So it's probably within 0.1° of each other or better. More than accurate enough for any wood work.

I’m sorry but I don’t know where to get replacement parts for that. As someone already said, it wouldn’t be hard to make one.

An aside. I think whether it’s better to repair vs replace has a lot of factors, some of which were already mentioned. But personally, I get some pleasure out of repairing a small item and then using it regularly in my (hobby) shop. Can’t tell you why. It’s not woodworking, but it’s enjoyable. (But I also like making tools and making things that organize my shop. For me, it’s not all about making furniture- for me. Maybe I’m odd that way.)

[Edward Weber]

One of the main issue with making this piece, is that it needs to be hardened. There is a lot of stress put on the small tang that holds the rule.
Also the threads need to be the correct length, too long and they will dig into the body, too short and you cant tighten the clamping enough.
Things to consider for those who like to tinker with such things.

[Jim Becker]

While there may be merit in trying to create a replacement piece just because it's interesting, for something like this that needs to work reliably and stay "square", I'd just buy a replacement square of good quality and move on. Using parts from other sources is certainly a possibility, but I suspect there is risk with an exact match and I say that from experience. I have both a Starrett combination square and a smaller Starrett "regular" square. A few years ago, I bought new scales for them as I wanted/needed metric scales. They were purchased from Lee Valley and are excellent. The rule for the combination was an absolutely perfect fit. The one for the smaller square works fine, but is harder to keep locked because there is some slight variability in the casting...it's an older square I bought pre-owned many years ago. The combo was also bought pre-owned, but was in like new condition and a newer vintage. So sourcing parts across brands "could" present minor (or major) fit differences "just because" there's no standard here.
